"Very happy with the service received. Booked online it was a very simple process that is efficient and convenient to use. Test completed quickly and within the time frame given and the staff are friendly and helpful."

"Great service a couple of bits needed sorting to pass the mot & the garage sorted them for a small fee. A couple of advisories but wasn’t pressured into getting them to sort them like most garages would."

"Helpful staff and fitted me in at short notice. As my car passed the test and the fee is a standard one I can't really make much comment. They seemed very professional though, and I would use them again."

"Great, very happy, the only problem is that with all my other cars I got a report back detailing all the items checked and whether they needed attention sooner rather than later. With this service all I got was an itemised invoice for parts and labour. No idea what was checked, what might need attention or anything."

What does a car diagnostic check do?

A diagnostic check is carried out on your vehicle by a mechanic, who will plug your vehicle into a specialised code reader. It can detect problems with your vehicle which may be difficult to spot manually.

The main components which are tested in a diagnostic check are the car’s:

electronic control units (ECUs) - these control various element of the car and its performance including engine running

emissions and exhaust sensors

braking system

electrical components such as central door locking

transmission if electronically controlled

ignition coils

throttle setting

fuel injectors

air flow and coolant

Why is a car diagnostic check important?

A diagnostic check is very important as it can detect a potential problem with your car, even before a breakdown. The computerised equipment scans your vehicle’s system to check for any faults, no matter how minor or major. A diagnostic test is a quick, easy and accurate way to discover any faults and will give you the chance to get them fixed before they turn into bigger and more expensive issues. When your car has a fault, this may show as a warning light on the dashboard. If the light goes out the system will store the fault code so the garage will find this when they do the diagnostic check.

What are the possible signs that your car needs a diagnostic check?

There are many different signs which will indicate that your vehicle needs a diagnostic check. Essentially, if you suspect that there is an issue with your car but don’t know what, you will probably want to book a diagnostic check to find out what the problem is. Here are some of the key signs:

Engine warning light - if the engine warning light appears on your dashboard, it’s important to take your vehicle to a garage as soon as possible as there is a wide variety of problems which the light may be flagging up.

Strange noises – any strange noises coming from your car need to be checked out before they turn into more serious problem. Some of these sounds may include; whining from the bonnet, abnormally loud exhaust, uneven engine noise, brake squealing or gear crunching.

Smoke - if you see smoke or steam coming from under the bonnet, your vehicle may be overheating.

Vibrating - if you notice any vibrating or pulling under your brake, the issue may be due to work brake discs or pads. However, it could also indicate a problem with your suspension or steering.

How long do car diagnostics take?

You can expect a diagnostic check on your car to take approximately 90 minutes. You may want to allow for more time though as the mechanic who will be carrying out the check might not be available to start right away.

How much does a car diagnostic check cost?

The price of a car diagnostic test can vary, depending on the garage that you visit. Each garage has a fixed price for diagnostic checks, ranging from £30 - £100.

About Subaru

Japanese firm Subaru’s heritage comes from the skies: the company developed out of the Nakajima Aircraft Company (1917-1945), which in its day was the largest aircraft manufacturer in Asia. In 1954 the company debuted its first automobile with the Subaru 500, Japan’s first mini, but Subaru’s story really started in 1972 with the launch of its symmetrical all wheel drive. It’s this factor above all which makes Subaru stand out from the crowd - 4x4 is standard on every car that Subaru sells in the UK (apart from the Justy city car).

Subaru currently sells seven models into the UK including the popular Outback, the original ‘crossover’ and a trusty and tough SUV. Other much loved models include the Forester, a slightly smaller SUV ideally suited to rural driving, and the Impreza - a rally champion turned practical family car.

Subaru owners display impressive brand loyalty, and for good reason. These cars are known for their longevity - it’s not unusual to see Foresters and Outbacks on the used car sales boards with over 200,000 miles on the clock. Part of the reason for this is Subaru’s unique flat-lying ‘boxer’ engines, with pistons which punch horizontally, like a boxer, rather than up and down as in a traditional engine. This means less vibration and friction, and better lubrication, particularly on start-up. In some ways, Subaru build cars which are seemingly almost indestructible! For safety and reliability across the board they consistently score very highly indeed with drivers and independent reviewers.

How to be a better driver

Whether you’re driving in Fleet or further afield, think about road user etiquette. Showing respect for other road users
makes driving more pleasant for you and safer for everyone. For example, if you have to make a last minute change of lane, make
your request to change clear to the driver who will need to let you in - and signal your thanks if they do. Be ready to abandon
the change of lane if they won’t play ball - your safety (and that of other drivers and pedestrians) is more important than
getting to your destination in the shortest time possible. When the position is reversed and a driver asks your permission to
change lanes, allow them to as long as it is safe. If you get frustrated, avoid using your horn - it won’t improve matters and
might make them considerably worse.
